Vivek,

That's right, the master thread also serves as a worker.

I need to obtain the thread IDs of all worker threads in facesim  
(built using pthreads). I was browsing through the code and found that  
the main loop created one thread less than the number specified  
(taskQDistCommon.c in the method taskQInit):

  for ( i = 1; i < numThreads; i++)

Does this mean that the main thread also acts as a worker thread? If  
not, where is the missing thread being created? This seems to be  
different from the strategy in blackscholes or bodytrack.
